A Hollywood monster movie producer is witness to the arrival of Dragoom, a convict from the planet Vulcan, on Earth. He wishes to be ruler of Earth and surrounds the planet with a band of fire which he slowly constricts until the authorities give in to his demand. The producer gets him to flee by constructing dummies that appear to be police from his homeworld.

Two robbers flee a crime scene and head towards the woods. One falls, breaking his leg, and the other ruthlessly shoots him as his identity may be found out by the police. Stopping at an abandoned house, the man sees two ghosts, but finds out they are creatures from another dimension, who can't touch him. The man laughs at the situation, imagining other people who have run from the house, believing it to be haunted. The creatures say that perhaps it was wise for them to run, as the man discovers when the police come into the house and he realizes he is trapped eternally between the two dimensions.

A ventriloquist and his dummy are chased by the mob who are trying to collect on Gambling debts. They eventually corner him in an alley way and presumably kill the ventriloquist before being arrested by the police. In the end it is revealed that the dummy itself is alive and the ventriloquist and the human is just a dummy.

A scientist invents a microscope so powerful that it can observe details of even the tiniest atom. He observes creatures making war upon one another and becomes depressed with his invention. He smashes it, so that his people will not have the opportunity to learn ways of destroying themselves that they had not yet thought of. He names the world that he had been observing "Earth".
